Product details
Overview
TLC2252AQPWRG4Q1 from Texas Instruments is a dual-channel, rail-to-rail output, automotive-qualified operational amplifier featuring 850 µV max input offset voltage at 25°C, 19 nV/√Hz input voltage noise at 1 kHz, and 35 µA per channel supply current. It operates from ±2.2 V to ±8 V supplies, supports common-mode input down to the negative rail, and delivers rail-to-rail output swing-ideal for precision signal conditioning in battery-powered automotive sensor interfaces.
For engineers reviewing the TLC2252AQPWRG4Q1 datasheet, TLC2252AQPWRG4Q1 pinout, TLC2252AQPWRG4Q1 application, or TLC2252AQPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, low-input-bias-current (1 pA typ), micropower operation, rail-to-rail output capability, and guaranteed performance across −40°C to 125°C.
Technical Context
The TLC2252AQPWRG4Q1 uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), ultra-low input bias current (1 pA typ), and rail-to-rail output swing with single- or split-supply operation. Its architecture enables stable unity-gain operation with 63° phase margin and 15 dB gain margin under 50 kΩ//100 pF load conditions.
It is fully specified for both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) configurations, with common-mode input range extending to the negative rail and output swing covering both supply rails. Input offset voltage is trimmed to ≤850 µV at 25°C and drifts at only 0.5 µV/°C over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide automotive battery voltage variation and robust single-supply 5 V operation |
| Input Offset Voltage (max) | 850 µV at 25°C - enables high-accuracy DC-coupled amplification without external trimming |
| Supply Current per Channel | 35 µA typ - allows multi-channel sensing in energy-constrained automotive modules |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - improves SNR in low-level transducer signal conditioning (e.g., piezoelectric sensors) |
| Common-Mode Input Range | Includes negative rail - permits direct interfacing with ground-referenced sensors and single-supply front-ends |
| Rail-to-Rail Output | Swing within 10 mV of both rails at light load - maximizes dynamic range when driving ADCs or low-voltage logic |
| ESD Rating | 2000 V HBM, 150 V MM - meets automotive system-level ESD immunity requirements |
Pinout & Package
TLC2252AQPWRG4Q1 is housed in an 8-pin TSSOP (PW) package, 3.0 mm × 4.4 mm, 0.65 mm pitch, with exposed pad for thermal enhancement (not electrically connected).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA; rail-to-rail swing supports full ADC input range utilization |
| 2 | IN1− | Inverting input of Amp1 - high-impedance node (10¹² Ω); sensitive to PCB leakage and layout parasitics |
| 3 | IN1+ | Non-inverting input of Amp1 - accepts signals from negative rail to VDD+ − 1.5 V in split-supply mode |
| 4 | GND / VDD− | Ground reference or negative supply - shared return path; requires low-impedance connection to minimize PSRR degradation |
| 5 | VDD+ | Positive supply - accepts up to +8 V; decoupling capacitor essential for stability and noise rejection |
| 6 | IN2+ | Non-inverting input of Amp2 - identical electrical behavior to Pin 3; enables dual-sensor buffering |
| 7 | IN2− | Inverting input of Amp2 - matched to Pin 2; supports differential configurations with common-mode rejection |
| 8 | OUT2 | Amplifier 2 output - independent channel; enables simultaneous signal conditioning for redundant or multi-axis systems |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into ADCs or low-voltage comparators without level-shifting circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432QDRQ1 | Higher output drive (60 mA), wider input voltage range (to VDD− − 0.3 V), but higher supply current (125 µA/ch) | Better suited for driving heavier capacitive loads or higher-current ADC references | Select TLV2432QDRQ1 when output short-circuit robustness or faster settling into 1000 pF loads is required |
| LM7332QMA/NOPB | Higher slew rate (10 V/µs), lower noise (12 nV/√Hz), but not rail-to-rail input and consumes 1.1 mA/ch | Targeted at high-speed, high-precision industrial control-not optimized for micropower automotive use | Choose LM7332QMA/NOPB only if bandwidth >1 MHz and THD+N <0.001% are mandatory, and power budget allows |
Compared with TLV2432QDRQ1 and LM7332QMA/NOPB, TLC2252AQPWRG4Q1 uniquely balances AEC-Q100 qualification, micropower consumption, rail-to-rail output, and sub-1 mV offset - making it optimal for cost-sensitive, thermally demanding, battery-aware automotive sensing nodes where efficiency and accuracy coexist.

FAQ
What is the maximum operating temperature range for TLC2252AQPWRG4Q1?
TLC2252AQPWRG4Q1 is qualified per AEC-Q100 Grade 1 and operates reliably from −40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and open-loop gain, ensuring consistent performance in under-hood and cabin-mounted automotive modules.
Does TLC2252AQPWRG4Q1 support single-supply operation?
Yes, TLC2252AQPWRG4Q1 supports true single-supply operation down to 4.4 V (e.g., 5 V nominal). Its common-mode input range extends to the negative rail (GND), and output swings rail-to-rail - enabling direct interface with microcontrollers and ADCs in 5 V automotive domains without level-shifting circuitry.
What is the input bias current specification for TLC2252AQPWRG4Q1?
TLC2252AQPWRG4Q1 has a typical input bias current of 1 pA at 25°C, with a maximum of 60 pA across the full −40°C to +125°C range. This ultra-low value preserves signal fidelity in high-impedance sensor interfaces such as thermistors, piezoelectric elements, and electrochemical sensors used in automotive applications.
Is TLC2252AQPWRG4Q1 pin-compatible with standard TLC2252 variants?
Yes, TLC2252AQPWRG4Q1 shares identical pinout and footprint with non-automotive TLC2252A variants in the TSSOP-8 (PW) package. However, it includes enhanced process controls, wafer-level testing, and qualification per AEC-Q100 - meaning mechanical and electrical compatibility is maintained while adding automotive reliability assurance.
How does the noise performance of TLC2252AQPWRG4Q1 compare to legacy micropower op-amps?
TLC2252AQPWRG4Q1 delivers 19 nV/√Hz input voltage noise at 1 kHz - approximately four times lower than prior-generation micropower CMOS op-amps like the TLC27L2. This improvement directly enhances signal-to-noise ratio in low-amplitude sensor front-ends, such as cabin air quality monitors or tire pressure sensor signal chains using TLC2252AQPWRG4Q1.
